The Antilles harbour several island endemic odonate species, including some palaeoendemics, within a relatively small and anthropized area. Such attributes give this archipelago a special significance for the conservation of Odonata in the Neotropics. However, despite the importance of these islands, inadequately surveyed regions persist, mainly in the Greater Antilles, and there is not enough…
Coenagrion mercuriale is a threatened damselfly in most parts of its geographic distribution. It is listed as endangered in North Africa, where no data on its biology or ecology are available. This study aims to illustrate the reproductive behaviour and habitat preferences of adults in a population located in north-east Algeria, representing the southern limit…
The last instar larva of Calopteryx exul Sélys is described and illustrated based on larvae collected from the Seybouse River (northeast Algeria) and reared in the laboratory. A comparative analysis of three other congeneric species is presented.
The aim of the study was to determine oviposition site selection in the endangered damselfly Coenagrion mercuriale in its UK stronghold and to determine hatching success of eggs. This was achieved by watching the behaviour of marked pairs from the onset of copulation to the end of oviposition and recording the number and duration of…
The state of knowledge of China’s Odonata is very much incomplete with many species awaiting description, especially from tropical and subtropical areas. A brief account is given of new odonate species described from China, including Taiwan, between 2000 and 2003. Information on identification guides, faunal lists and current studies, is provided. Species of Odonata, categorised…
Of the 86 Odonata species so far recorded for the Levant, four are considered as endangered (Calopteryx hyalina, C. syriaca, Ceriagrion georgifreyi, Pseudagrion torridum hulae), six as vulnerable (Coenagrion vanbrinckae, P. sublacteum mortoni, Gomphus kinzelbacbi, Onychogomphus macrodon, Brachythemis fuscopalliata, Crocotbemis sanguinolenta), and two as extinct (Rhyothemis semihyalina syriaca, Urothemis edwardsi hulae). The history of odonatological…
Altogether 116 odonate species are known from Sri Lanka. The level of endemism is high -53 taxa or 45.7% are confined to the island. The Chlorocyphidae, Euphaeidae, Protoneuridae, Platystictidae, Gomphidae and Corduliidae consist of almost exclusively endemic taxa. The odonate fauna of Sri Lanka is still insufficiently known. Knowledge on distribution, biology and taxonomy of…
The region is broadly determined by desert, which forms a huge belt between the western Palaearctic and the Afrotropics. Fourteen out of the 125 odonate species recorded so far are endemics. There are two main centres of endemism in the region: the northern Maghreb and the southern Arabian Peninsula. Odonate habitats in the desert are…
Western Africa—defined as the tropical area from Cameroon westwards—probably has the richest odonate fauna in Africa, particularly the region of (and around) the Cameroon highlands. This region is home to many relict and endemic species, such as the continent’s only representatives of the families Amphipterygidae and Perilestidae. Previous selections of threatened West African Odonata have…
The Australian Odonata fauna is reviewed. The state of the current taxonomy and ecology, studies on biodiversity, studies on larvae and the all identification keys are reported. The conservation status of the Australian odonates is evaluated and the endangered species identified. In addition the endemic species, species with unusual biology and species, not threatened yet,…
